Chemists at Newcastle University (Newcastle, U.K.) say they are progressing “extremely well” and may now be about four years from commercializing an energy-efficient process for converting waste carbon dioxide (CO2) into commercially-useful chemical compounds including cyclic carbonates. The technology uses a novel, highly reactive dimetallic aluminum salen-based catalyst. The process has the potential to convert up to 48 million m.t./year of waste CO2-equivalent to 4% of the U.K’s total CO2 emissions, according to Michael North...
